Seemed to have lost the ability for ringtonesGeneral

Soooo....Eris was complaining that I didn't have enough memory. So I went to clear out some room for the whine a**. Data? Psssshhhht...who needs that? Well apparently I do to have uh, ringtones. I have none. When I try to set my ringtone, nothing comes up. So apparently I deleted something I need. Can't access any of my music either. Any one got an idea how to fix this? It's doing that scroll to the left thing too, maybe I'll just get a new one until I can upgrade.

And just a thought, how is it that I can delete the ability to have a ringtone, but I can't delete Amazon Mp3 Store????
